TROPICAL STORM 25L (GAMMA) PUBLIC ADVISORY #6 FORCE THIRTEEN SINGAPORE, SINGAPORE 1520 UTC MON OCT 5 2020 ...GAMMA LIKELY TO BECOME A REMNANT LOW... SUMMARY OF 1500 UTC...INFORMATION ----------------------------------- LOCATION...NEAR 22.3 N 87.6 W... MAXIMUM SUSTAINED WINDS...45MPH...75KM/H MINIMUM CENTRAL PRESSURE...1003MB WATCHES AND WARNINGS ----------------------------------- A Tropical Storm Warning is in effect for... * North and west of Cancun to Dzilam Mexico A Tropical Storm Watch is in effect for... * West of Dzilam to Campeche Mexico![]()
DISCUSSION ----------------------------------- Air Force Reserve reconnaissance aircraft investigating Gamma found maximum 850 mb flight-level winds of 37 kt and surface SFMR peak winds of 40 kt, and the central pressure has increased to 1003 mb. Therefore, the initial intensity is lowered to 40 kt for this advisory. Stiff, persistent southerly shear, and an inhibiting thermodynamic surrounding environment should prevent Gamma from restrengthening, although, the Decay SHIPS intensity model does indicate a very brief period of decreasing shear magnitude just prior to landfall around the 24 hour period. Afterward, the shear, once again, increases. Gamma is expected to make landfall over the northwestern Yucatan peninsula on Tuesday and further weakening to a remnant low is forecast Wednesday as the cyclone remains inland over the northern Mexican State of Yucatan. Dissipation is likely to occur Friday over the region, if not sooner.
